Iterate among all buffers that are displayed (i.e., have a window), widening each: (defun foo () "..." (interactive) (dolist (buf (buffer-list)) (when (get-buffer-window buf 0) (with-current-buffer buf (widen))))) Or if you want to do it to all (live) buffers, even if they aren't displayed in a window, then this: (defun foo () &...

One way to do it is by comparing the current-time with the buffer-display-time. If the gap is small enough it means it was most likely a buffer change that ran the hook. (defun my-test-scroll-or-buffer-change (window _window-start-after) (with-selected-window window (if (> 0.001 (float-time (time-subtract (current-time) buffer-display-time))) ...

I took a look at the implementation of switch-to-prev-buffer (thanks Tobias! I didn't think to look there…), found the function window-prev-buffers and came up with this: (defun previous-buffer-cycle () "Switch to the buffer previously displayed in the current window." (interactive) (pop-to-buffer-same-window (caar (window-prev-buffers)))) I ...

Doc-string of the command previous-buffer: In selected window switch to ARGth previous buffer. Call switch-to-prev-buffer unless the selected window is the minibuffer window or is dedicated to its buffer. It is bound to C-x C-left. There is also the command mode-line-previous-buffer which does the same as previous-buffer but first selects the window from ...

C-x 5 2 does what you request: it opens the current buffer in a separate frame. But it does not delete the original window showing the buffer in the original frame. Command tear-off-window does both: opens the buffer in a separate frame and deletes its window from the original frame. Personally, I bind tear-off-window to C-x 5 1. (I don't use that key's ...

What about (defun switch-buffer-delete-other-windows () (interactive) (call-interactively 'switch-to-buffer) (delete-other-windows)) (defun find-file-delete-other-windows () (interactive) (call-interactively 'find-file) (delete-other-windows)) and so on…?
